IMPROVEMENT IN NURSING-BOTTLES.

Specification forming part of Letters Patent No. 120,575, dated November 7, 1871.

To all 'whom it may concern:

Be it knownthat I, LEMUEL PoMnnov Denen, of the city and county of New York, in the State of New York, have invented a new and useful Improvement in Feeding-Bottles 5 and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing making part of this specification, in which- Figure l is a diametrical section through the improved feeding-bottle. Fig. 2 is an external view of the bottle with the nipple-tube broken off. Fig. 3 is a View of the India-rubber valve.

Similar letters of reference indicate corresponding parts in the several figures.

The object of this invention is to improve feeding or sucking-bottles for infants by the application to a perforated stopple of an India-rubber ring which has one or more slits through it, as will be hereinafter explained, whereby air is allowed to enter the bottle freely while sucking, but the iiuid is prevented. from escaping around the stopple or through the air-inlet.

The following descripton of my invention will enable others skilled in the art to understand it.

The bottle A and the nipple-tubes O C and nipple D may be constructed in the usual wellknown manner., The stopple B, which is preferably made of glass and adapted to fit tightly into the neck of the bottle A, is constructed with va head, b, beneath which is a contracted annularly-grooved neck, that is perforated at c for the admission of air. The perforation c allows air from without to enter bottle through the opening for receiving the tube C, as shown in Fig. l. Around the said neck an India-rubber ring, a, (made of iia't rubber,) is applied, which has one or more short slits made through it, as shown by Figs. l and 3.

l/Vhen iiuid is drawn from the bottle through the nipple-tubes air will enter the bottle and supply its place through the slits made through the rubber ring a and through the aperture c. The fluid will not, however, escape through the airinlet, as the slits will be closed like a valve, eX- cept to the admission of air when the mouth is applied to the nipple.

It will be seen that this device is a very simple one, and that it will not be liable to get out of order.

The ring-valves a can be renewed from time to time should they become inoperative, and they can be readily removed when it is desired to clean the stopple, and with equal facility replaced.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, 1S.-

The stopple B for a feeding-bottle, perforated at c and provided with a'l slit ring-valve, a, substantially as described.

LEMUEL POMEROY DODGE.
